WOVEN PILE FABRIC.

Specification of Letters Patent.

PatentedJ'uly 2, 1907.

Application filed October 11, 1906; Serial No. 338,423.

To all whom it may concern:

Be it known that I, EDWARDF. TIMME, a citizen of the United States, anda resident of Spring Valley, in the county of Rockland and State ofNewYork, have invented a new and Improved Woven Pile Fabric, of which thefollowing is a full, clear, and exact description.

The invention relates to plush fabrics usually woven double or face toface, and its object is to provide a new and improved woven pile fabric,in which the pile is securely bound in place, to prevent the piles frombeing pushed out at the back of the fabric when the latter is used andbrushed. g

The invention consists essentially of a body formed of ground warpthreads and weft threads, and pile threads looped around the weft threadand covered at the back of their loops by the ground warp threads.

The invention also consists of novel features and parts and combinationsof the same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is repre-- sented in theaccompanying drawings forming a part of this specification, in whichsimilarcharacters of reference indicate corresponding parts in all theviews.

Figure 1 is an enlarged sectional side elevation of the improvement,showing a pair of ground warp threads and one of the pile threads of aset; Fig. 2 is a like view of the improvement showing the next followingpair of ground warp threads and the other pile thread of the set; Fig. 3is a sectional side elevation of the improvement showing the successivepairs of ground warp threads, and a set of pile threads, and Fig. 4 is atransverse section of the same on the line 44 of Fig. 3.

In the ordinary plush fabrics as heretofore constructed the backs of thepile loops appeared unpro-' tected on the back of the fabric, and hencethe piles were liable to work out at the back when a pressure wasapplied on the face of the fabric, and this was especially the case whena stiff fiber like mohair, wool or the like was used for the pilethreads. To overcome this defect it has been proposed to use an extra oradditional floating warp thread, as shown, for instance, in the LettersPatent of the United States, granted to J. Reixach, No. 442,749, onDecember 16, 1890. This additional floating ground warp thread rendersthe fabric more expensive.

With my invention presently to be described in detail, the regularground warp threads pass over and cover the backs of the pile loops, andhence the pile loops are not visible on the back and are securely heldagainst a backing-out movement.

The cloth A, as shown in the drawing, has its body formed of two pairsof ground warp threads 0, O, and C C and weft threads D, D, D D and thebody of the opposite cloth B is formed of two pairs of ground warpthreads 0 C and G, G and the weft threads D D D and D The groundwarpthreads of each cloth A and B are interwoven with the corresponding weftthreads, three up and one down, so that the weaving is repeated, aftereach four picks, as will be readily understood by reference to thedrawings. The pile threads crossing from one cloth to the other arearranged in sets, two pile threads E and E being in each set and loopedaround alternate weft threads in each cloth A and B. Thus the pilethread E (see Fig. l) is looped around the weft thread D in the cloth A,then crossed over to other cloth B and looped around the weft thread Dto then return to the cloth A, and looped aroundthe weft thread D and soon, and the other pile thread E (see Fig. 2) is.looped around the weftthread D of the cloth B and'then crossed over to the cloth A and loopedaround the weft thread D, then passed back to the cloth B and loopedaround the weft thread D and so on.

Of the pair of ground warp threads 0 and C the ground warp thread 0 (seeFig. 1) passes over and covers the back of the loops formed by the pilethread on the weft threads D, D D in the cloth A, and the other groundwarp thread C passes over the said weft threads D, D D adjacent to thesaid pile thread E. The next following pair of ground warp threads 0 Cfor the cloth A is similarly arranged (see Fig. 2), that is, the groundwarp thread 0 passes over and covers the backs of the loops of the pilethread E, at the weft threads D, D D while its mate, the ground warpthread C passes over the said weft threads D, D D adjacent to the loopsof the said pile thread E.

The pairs of ground warp threads 0 Q and C, C for the cloth B arearranged similar to the ones for the cloth A and as above described,that is, the ground warp threads C and C pass over and cover the backsof the loops of the pile threads E and E at the weft threads D D and D,D respectively, and the ground warp threads C 0 pass over the weftthreads D D and D, D adjacent to the loops of the pile threads E and E,respectively. It will also be noticed that the weft threads in the clothA and over which pass the pair of ground warp threads 0, O and the pilethread E (see'Fig. 1) is bound in by and passes between the nextfollowing pair of ground warp threads 0 C and the weft thread in thesame cloth A and over which pass the ground warp threads C C and thepile thread E is bound in and passes between the next following pair ofground warp threads G, C. The same arrangement is found in the cloth Brelative to the weft threads, the ground warp threads and the pilethreads forming this cloth.

In order to produce the desired result, that is, to utilize the regularground warp threads, for covering and binding in place the backs of thepile loops, a special arrangement in the mechanism of the loom forweaving States for a loom for weaving the fabric is necessary and suchas shown and'deserib ed in the application for Letters Patent of theUnited pile fabrics, #342,040, filed by Frederick O. Pfeifier onNovember 5, 1906.

It is understood that the drawings illustrate the fabric very muchdistorted and exaggerated, and in practice the back of a pile thread isliable to shift sufiiciently transversely so as to be covered and boundin by adjacent warp threads 0 and O and still not protrude through theback.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:

1. A woven pile fabric comprising a single body formed of regular groundwarp threads and weft threads, and pile threads looped around the weftthreads, the backs of the pile loops being solely overlaid and concealedby the said regular ground Warp threads.

2. A woven pile fabric comprising regular non-floating ground warpthreads, weft threads interwoven with the said regular non-floatingground warp threads, and pile threads looped around the said weftthreads, the pile threads being arranged in sets and looped aroundalternate weft threads, the backs of the pile loops being solely coveredby the said regular nonfloating ground warp threads.

3. A woven pile fabric comprising ground warp threads, weft threadsinterwoven with the said ground warp' threads, the latterbeing arrangedthree up and one down, and pile threads arranged in sets, of which onein a set is looped around alternate weft threads and the other in thesame set is looped around the remaining weft threads, the backs of thepile loops being covered by the said ground warp threads.

4. A woven pile fabric comprising ground warp threads, weft threadsinterwoven with the said ground warp threads, the latter being arrangedthree up and one down, and pile threads arranged in sets, of which onein a set is looped around alternate weft threads and the other in thesame set is looped around the remaining weft threads, the said groundwarp threads being arranged in pairs one pair for each pile thread in aset, one of the ground warp threads in a set passing over and coveringthe backs of the loops of the said pile thread in a set.

5. A woven pile fabric comprising ground warp threads, weft threadsinterwoven with the said ground warp threads, the latter being arrangedthree up and one down, and pile threads arranged in sets, of which onein a set is looped around alternate weft threads and the other in thesame set is looped around the remaining wei't threads, the said groundwarp threads being arranged in pairs, one for each pile thread in a set,one of the ground warp threads in a set passing over and covering thebacks of the loops of the said pile threads in a set, and the otherground warp thread of this set extending over the weft thread to oneside of the pile thread covered by the other ground warp threads of thepair.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
